FR-4 copper clad laminated sheet uses glass fiber cloth as substrate material. After being immersed with epoxy resin and then baked into prepreg sheet, several prepreg sheets are then coated with copper foil on one side or both sides, and CCL is finally formed by hot pressing and curing.

FR-4 copper clad laminated sheet has excellent thermal stability and machinability, widely used in the manufacture of printed circuit board (PCB) for television sets, computers, communications equipment and other electronic products.

It is a kind of copper foil covered laminated board formed through heat pressing after the electric industry alkali-free glass fiber dips into thermoset epoxy resins and is covered with copper foil at one side or both sides, called copper-clad laminate(CCL) .It is used for production of printed circuit board(PCB).
